For the most part, the groupings look as you might expect -- Texas A&M's Luke Joeckel is the top offensive tackle, West Virginia's Geno Smith is the top quarterback, and Alabama's Dee Milliner is the first cornerback listed -- but there are a few surprises.

Leading the way is the center rankings, where Mayock places both Wisconsin's Travis Frederick and Cal's Brian Schwenke ahead of MLive readers favorite, Barrett Jones from Alabama.

Frederick is massive for the position. A former guard, he's listed at 6-foot-4, 334 pounds.
